Modeling and Similitude

Modeling and Similitude

Scaled modeling is a fundamental technique in engineering, enabling the study of large and complex systems by creating smaller, manageable replicas that recreate critical characteristics of the original. In hydrology and civil infrastructure, for example, scaled models of dams help analyze water flow, turbulence, and pressure. This method allows for accurate predictions of real-world behavior within a controlled environment, significantly reducing the cost and time involved in full-scale...

Impact of Schemas

Impact of Schemas

Schemas are cognitive structures that provide a framework for interpreting and organizing social information. They help individuals navigate complex environments by offering expectations about people, events, and behaviors. Schemas influence attention, encoding, and retrieval processes, thereby shaping the entire trajectory of information processing in social contexts.Attention and Cognitive LoadDuring initial attention, schemas function as filters that prioritize schema-consistent information,...

Methods of Documentation II: POMR

Methods of Documentation II: POMR

The Problem-Oriented Medical Record (POMR) revolutionized medical record-keeping by introducing a systematic approach focusing on the patient's problems rather than merely listing symptoms. Dr. Lawrence Weed's introduction of this method in the 1960s marked a significant advancement in medical documentation. The POMR framework consists of four key components: the database, problem list, plan of care, and progress notes.

Methods of Documentation I: Source-Oriented Records

Methods of Documentation I: Source-Oriented Records

Source-oriented records, or SOR, are medical record-keeping organized by the data source. The SOR system was first developed in the mid-1900s to organize the growing patient data in hospitals and other healthcare facilities.
In an SOR, each discipline involved in patient care maintains a separate medical record section. This record-keeping method enables easy tracking of patient progress and ensures healthcare staff have access to up-to-date information.
Key Attributes include the following:

Mechanistic Models: Overview of Compartment Models

Mechanistic Models: Overview of Compartment Models

Mechanistic models, a category encompassing both physiological and compartmental modeling, differ from empirical models' approaches to incorporating known factors about the systems being modeled. Empirical models describe data with minimal assumptions, while mechanistic models aim to provide a robust description of available data by specifying assumptions and integrating known factors about the system. Compartmental analysis is a key example of a mechanistic model in pharmacokinetics and...

Stereotype Content Model

Stereotype Content Model

The Stereotype Content Model (SCM) was first proposed by Susan Fiske and her colleagues (Fiske, Cuddy, Glick & Xu, 2002; see also Fiske, 2012 and Fiske, 2017). The SCM specifies that when someone encounters a new group, they will stereotype them based on two metrics: warmth—or that group’s perceived intent, and how likely they are to provide help or inflict harm—and competence—or their ability to carry out that objective. Depending on the warmth-competence categorization, a person will feel...

Area of Science:

Biomedical Informatics
Data Standards
Information Management

Background:

Data interoperability is crucial for organizations, relying on agreed-upon metadata meaning and representation.
Metadata Registries (MDRs) are often built using the ISO/IEC 11179 standard, with notable examples in the biomedical domain like USHIK and caDSR.
Custom extensions to MDRs for organizational needs and limitations of ISO/IEC 11179 hinder interoperability between different MDRs.

Purpose of the Study:

To propose an integrated metadata object model for achieving interoperability among multiple MDRs.
To develop an evaluation method for the proposed model.
To facilitate seamless data exchange across diverse biomedical data repositories.

Main Methods:

Development of an integrated metadata object model.
Creation of an XML Schema Definition (XSD)-based metadata exchange format to support the model.
Implementation of an XSD-based metadata exporter compatible with both the integrated model and organization-specific MDR formats.

Main Results:

The proposed integrated metadata object model provides a framework for unifying disparate MDRs.
The XSD-based exchange format and exporter enable practical metadata exchange.
Demonstrated ability to support both the integrated model and existing organization-specific MDR formats.

Conclusions:

The integrated metadata object model is effective in addressing the challenge of interoperability among multiple MDRs.
The developed XSD-based tools facilitate standardized data exchange in the biomedical domain.
This approach enhances the potential for broader data sharing and collaborative research through improved data interoperability.
